When the 661 first came along, I ported one and got a 15% gain. I thought that was horrible, so I ordered another top end to try again. That was when the recall happened. Took me a couple of months to get that top end. After trying again, I got about a 25% gain. I figured that was as good as it was gonna get. Now, I've done over 60 of these saws, and am getting around a 40% increase in cut speed. To be honest.....the "recipe" I ended up with was sort of an accident. We called that saw El Freako because I was sure I couldn't duplicate it. But......I was able to, and have been building them that way for about two years now. To let you guys know how those of us that build saws really are, this saw - El Freako - was sent to Scott and Julian to try against the saws Scott builds. There was no butt hurt......no ********......no drama. Just friends doing what friends do.
My point is this......the 462 is a brand new saw. And.....it's weird as a mfer. The transfer entrances are in the bottom of the case, and they are contrary to crankshaft windage. I took the first one apart a few times and just scratched my head. But......I've managed some solid gains on the saw by just building upon what I think is good about the design. I actually have 5 new ones here right now......doing them that way allow me to make small changes to each saw, and run them against each other to see if I'm going in the right direction.
It's gonna take a few more saws to get a solid "recipe" for the 462. I'd never claim to have it figured out at this point......but I can promise an solid increase in torque that allows the faller to run a more aggressive chain, or a larger sprocket. I'm not looking for more rpm......just a wider, and flatter powerband. At least for now.
